How to format my macbook

My macbook pro is about 1 1/2 year old and i started having problems with permissions and likely also the library. I want to start from scratch, how do i reformat the HD and reinstall the software?

Before you go through all of that, just reinstall Lion over itself. Reboot holding Command-R, reinstall Lion & see how things are.

    If you are entitled to download Mountain Lion, because you have paid for it or it was on your computer when you bought it from Apple, you can place it on a flash drive.

    And the cost, from the App store when you purchase for the first time, is US$20.00 (twenty).

    Format and reinstall everything is a drastic measure. If you describe the issues in detail perhaps a resolution can be found.

    how can i format my macbook 10.5.8 to snow leopord i am doing first time  format how its process and do i need to formet or upgrade and i have a snow leopard DVD???

    First, I'd advise you to make a backup. Time Machine is fine, but I recommend making a bootable backup with Carbon Copy Cloner if possible.
    Then, insert the Snow Leopard DVD (it's a retail version, right? Not a grey disk meant for another machine?) and run the installer on the disk. Should be automatic from that point in. You don't need to reformat your drive.

    i formated my macbook pro with windows 7 and i lost all the drivers, does anyone know how to recover the drivers?

    How did you get them to install the first time and where did you get them?
    Read the Installation Guide, Boot Camp 4.0 FAQ and the Windows 7 FAQ.
    Here's the Boot Camp Manual.

  • HOW TO RESET MY MACBOOK PRO MD976 AS I WANT TO DELETE ALL DATA FROM MACBOOK

    how do i reset macbook pro MD976 to factory setting ? , cause i want to sell it .

    Follow these instructions step by step to prepare a Mac for sale:
    Step One - Back up your data:
           A. If you have any Virtual PCs shut them down. They cannot be in their "fast saved" state. They must be shut down from inside Windows.
           B. Clone to an external drive using using Carbon Copy Cloner.
              1. Open Carbon Copy Cloner.
              2. Select the Source volume from the Select a source drop down menu on the left side.
              3. Select the Destination volume from the Select a destination drop down menu on the right
                  side.
              4. Click on the Clone button. If you are prompted about creating a clone of the Recovery HD be
                  sure to opt for that.
                   Destination means a freshly erased external backup drive. Source means the internal
                   startup drive.
    Step Two - Prepare the machine for the new buyer:
              1. De-authorize the computer in iTunes! De-authorize both iTunes and Audible accounts.
              2, Remove any Open Firmware passwords or Firmware passwords.
              3. Turn the brightness full up and volume nearly so.
              4. Turn off File Vault, if enabled.
              5. Disable iCloud, if enabled: See What to do with iCloud before selling your computer.
    Step Three - Install a fresh OS:
         A. Snow Leopard and earlier versions of OS X
              1. Insert the original OS X install CD/DVD that came with your computer.
              2. Restart the computer while holding down the C key to boot from the CD/DVD.
              3. Select Disk Utility from the Utilities menu; repartition and reformat the internal hard drive.
                  Optionally, click on the Security button and set the Zero Data option to one-pass.
              4. Install OS X.
              5. Upon completion DO NOT restart the computer.
              6. Shutdown the computer.
         B. Lion and Mountain Lion (if pre-installed on the computer at purchase*)
             Note: You will need an active Internet connection. I suggest using Ethernet if possible because
                       it is three times faster than wireless.
              1. Restart the computer while holding down the COMMAND and R keys until the Mac OS X
                  Utilities window appears.
              2. Select Disk Utility from the Mac OS X Utilities window and click on the Continue button.
              3. After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click
                  on the Erase tab in the DU main window.
              4. Set the format type to Mac OS Extended (Journaled.) Optionally, click on the Security button
                  and set the Zero Data option to one-pass.
              5. Click on the Erase button and wait until the process has completed.
              6. Quit DU and return to the Mac OS X Utilities window.
              7. Select Reinstall Lion/Mountain Lion and click on the Install button.
              8. Upon completion shutdown the computer.
    *If your computer came with Lion or Mountain Lion pre-installed then you are entitled to transfer your license once. If you purchased Lion or Mountain Lion from the App Store then you cannot transfer your license to another party. In the case of the latter you should install the original version of OS X that came with your computer. You need to repartition the hard drive as well as reformat it; this will assure that the Recovery HD partition is removed. See Step Three above. You may verify these requirements by reviewing your OS X Software License.

  • Backed Up from macbook pro to external hard drive for use on PC--how to restore to macbook pro?

    Good evening,
      My college student daughter uses her macbook pro, 13" Mid-2010,  for ALL her school work.  A few days ago it stopped working for her.  Blank screen.  Turned it off and on, blank screen with the gear spinning.  She took it to a place named MacExperience in Indy for diagnositcs.  The tech got it working and said it was OK now ($90 later).  Two hours later, same thing occurred.  She returned to the tech and he indicated it is in fact the logistics board that needs repair/replacement. 
    She purchased an external hard drive (G-Drive 500 GB mini FW800/USB 2/FW400 7200 RPM)--that is the description from the receipt she scanned and sent to me.   The tech backed up her files from the MBP to the  External HD so that the files are usable on a PC until the MBP is repaired.
    Will her files be intact on the MBP once it is repaired?  More importantly, since the back-up was made from the MBP to use on a PC, how do we restore the files from the external HD back to the MBP so that she can use MBP with all her files, school work, etc.?
    The tech said he will do it, but of course for another $90.  My point is, she needs to know how to do this in the event something like this occurs again (I sure hope not!!).  Furthermore, she will from now on back-up her files to the external HD, which she needs to learn to do, as well.
    Thank you for your helpful replies.

    I may be wrong, but I believe the format has something to do with it - note the sizes here (from the Help in Disk Utility on how to format a drive for Windows):

  • How do I get macbook air to boot up off of the network

    how do i get macbook air to boot up off of the network

    Install Mavericks, Lion/Mountain Lion Using Internet Recovery
    Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
    Boot to the Internet Recovery HD:
    Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
    Partition and Format the hard drive:
    Select Disk Utility from the main menu and click on the Continue button.
    After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
    Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
    Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
    Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
    This should restore the version of OS X originally pre-installed on the computer.
